摘　　要：针对黄河龙羊峡光伏电站与水电站联合运行短期调度的可行性问题,建立调峰能力最大数学模型,提出基于模拟优化思想的模型求解方法。通过反推机组的最大技术出力论证水光互补对系统调峰能力以及水电站群短期水量调度的影响。实例研究表明:水-光电联合运行短期内可进一步提高系统的调峰能力,且对下游梯级水电站群的日水量调度基本无影响。To validate the feasibility of the short-term scheduling for the joint operation of hydropower plant and photoelectric plant of LYX, a model aimed at maximizing the peaking capacity was set up. Meanwhile, a method basedon simulation and optimization was used to solve the proposed model. By estimating the maximum technical output of the hydro-photovoltaic system, the impact on hydropower peaking capacity and short-term water regulation was analysed, respectively. Case study reveals that the joint operation of hydropower and photoelectronic could further increase the peaking capacity of the system. In addition, this kind of operation mode has few adverse effects on the short-term water regulation of the downstream cascade reservoirs.
